Hi,
Thanks for your Reply.The Problem I face is there is a word called Geoffrey
Romer in my Field.
I am Forming a Multiphrase query object properly like " Geoffrey Romer".But
When i do a Search,it is not returning Hits.This Problem I am facing is not
for all phrases
This Problem happens for only few Phrases.
When i do a single query like Geoffrey it is giving a Hit..But when i do it
in MultiphraseQuery it is not able to find "geoffrey". I confirmed this by
doing trm.seekCeil(new BytesRef("Geoffrey")) and then and then when i
do String s = trm.term().utf8ToString().It is pointing to a diffrent word
instead of geoffrey.seekceil is working properly for many phrases though.
What could be the problem..please kindly suggest.
